The TW 190TDHBA chipper has the ability to adjust the towhead height to correspond with the 

vehicles towing point. 

The preferred towing angle of any chipper is with the 

1 

chassis level to the ground. The adjustable head has 

the ability to move between 300mm from the ground 

to 875mm giving an overall adjustment of 575mm. 

The towhead latch and handbrake fundamentally 

work the same as a fixed standard towhead, 

however the front section of the head is retained in 

position via a locking ring and single clamp handle. 

To adjust the height the locking handle located on 

the side of the head (1) is turned in an anticlockwise 

direction to allow for the locking ring to disengage 

from its apposing ring. An internal damper is fitter to 

support the heads weight allowing both hands free 

to adjust the height. Once the desired height has 

been achieved the locking handle is turned 

clockwise until tight. The latching of the hitch is as normal as is the fitting of the light plug and 

breakaway cable as outlined in the ‘Hitching onto the tow ball’ section on page 9.

WARNING 

The chipper will feed material through on its own. To do this, it relies on 

sharp blades on the chipper rotor. To keep the blades sharp, only feed the 

machine with clean brushwood. DO NOT put muddy/dirty wood, roots, 

potted plants, bricks, stones or metal into the chipper. 

OPERATOR'S PERSONAL PROTECTIVE EQUIPMENT REQUIRED 

Chainsaw safety helmet 

fitted with mesh visor and 

recommended ear defenders 

to the appropriate 

specifications. 

Work gloves with 

elasticated wrist. 

Steel toe cap safety boots. 

BASIC WOODCHIPPING SAFETY 

The operator should be aware of the following points: 

MAINTAIN A SAFETY EXCLUSION ZONE around the chipper of at least 10 metres for the 

general public or employees without adequate protection. Use hazard tape to identify this 

working area and keep it clear from debris build up. Chips should be ejected away from any 

area the general public have access to. 

HAZARDOUS MATERIAL - Some species of trees and bushes are poisonous. The chipping 

action can produce vapour, spray and dust that can irritate the skin. This may lead to 

respiratory problems or even cause serious poisoning. Check the material to be chipped before 

you start. Avoid confined spaces and use a facemask if necessary. 

BE AWARE when the chipper is processing material that is an awkward shape. The material 

can move from side to side in the funnel with great force. If the material extends beyond the 

funnel, the brash may push you to one side causing danger. Badly twisted brash should be 

trimmed before being chipped to avoid thrashing in the feed funnel. 

BE AWARE that the chipper can eject chips out of the feed funnel with considerable force. 

Always wear full head and face protection. 

ALWAYS work on the side of the machine furthest from any local danger, e.g. not road side. 

! 

Close fitting heavy-duty 

non-snag clothing. 

Face mask if 

appropriate. 

DO NOT 

wear rings, bracelets, 

watches, jewellery or any 

other items that could be 

caught in the material and 

draw you into the chipper.

ALWAYS stop the chipper engine before making 

any adjustments, refuelling or cleaning. 

ALWAYS check rotor has stopped rotating and 

remove chipper ignition key before maintenance 

of any kind, or whenever the machine is to be left 

unattended. 

ALWAYS check the machine is well supported 

and cannot move. 

ALWAYS operate the chipper with the engine set 

to maximum speed when chipping. 

ALWAYS check (visually) for fluid leaks. 

ALWAYS take regular breaks. Wearing personal 

protective equipment for long periods can be 

tiring and hot. 

ALWAYS keep hands, feet and clothing out of 

feed opening, discharge and moving parts. 

ALWAYS use the next piece of material or a push 

stick to push in short pieces. Under no 

circumstances should you reach into the funnel. 

 

ALWAYS keep the operating area clear of people, 

animals and children. 

ALWAYS keep the operating area clear from 

debris build up. 

ALWAYS keep clear of the chip discharge tube. 

Foreign objects may be ejected with great force. 

ALWAYS ensure protective guarding is in place 

before commencing work. Failure to do so may 

result in personal injury or loss of life. 

ALWAYS operate the chipper in a well ventilated 

area - exhaust fumes are dangerous. 


GENERAL SAFETY MATTERS 

DO’S AND DON’TS 

DO NOT operate chipper unless available light is 

sufficient to see clearly. 

DO NOT use or attempt to start the chipper 

without the feed funnel, guards and discharge 

unit securely in place. 

DO NOT stand directly in front of the feed funnel 

when using the chipper. Stand to one side. 

DO NOT allow - 

BRICKS STRING CLOTH PLASTIC STONES 

METAL GLASS RUBBER ROOTS BEDDING

THE chipper is now fully detached from the vehicle.


DELIVERY 

All Timberwolf 190TDHB (Turbo) machines have a full pre - delivery inspection before leaving the factory 

and are ready to use. Read and understand this instruction manual before attempting to operate the 

chipper. In particular, read pages 6-8 which contain important health and safety information and advice. 

OPERATOR’S PERSONAL PROTECTIVE EQUIPMENT REQUIRED 

CHAINSAW SAFETY HELMET fitted with visor 

and recommended ear defenders to an 

appropriate specification. 

HEAVY-DUTY work gloves with elasticated wrist. 

Control Panel Diagram 

See page 6 for more detailed information. 

MANUAL CONTROLS 

CLOSE - FITTING heavy-duty non-snag clothing. 

SAFETY footwear. 

FACE MASK (if appropriate). 

Roller control box - is the control box above the feed opening of the chipper funnel. Its function is to control 

the feed rollers. The feed rollers draw material into the machine. It does not control the main rotor. 

RED SAFETY BAR = This is the large red bar that surrounds the feed tray and side of the feed 

funnel. The bar is spring loaded and connected to a switch that will interrupt the power to the rollers. 

The switch is designed so that it only activates if the bar is pushed to the limit of its travel. The rollers 

stop instantly, but can be made to turn again by pressing either the GREEN FEED or BLUE REVERSE 

control buttons. 

RED SAFETY BAR TEST 

To ensure the safety bar is always operational it must be activated once before each work session. 

The rollers will not function until the bar is activated. This procedure must be repeated each time the 

ignition is switched off. 

WARNING 

DO NOT remove, jam, disable, bypass, override or otherwise 

impede the effectiveness of the red safety bar. 

! ! 

GREEN BUTTON = Forward feed - Push the button once - this activates the rollers and will allow you 

to start chipping (if the rotor speed is high enough). 

RED BUTTON = Emergency stop - This button stops the rollers from feeding. It overrides all other 

buttons or bars and will not allow the other buttons to function until it has been reset. To reset, pull out until 

it returns to its original position. The forward and reverse buttons will now function. 

BLUE BUTTON = Reverse feed - allows you to back material out of the rollers. The rollers will only 

turn in reverse as long as you keep pressing the button. You do not have to press the STOP button 

before pressing the GREEN FEED button to recommence feeding.

AUTO CONTROLS 

The engine management unit controls the feed rate of the material going into the chipping chamber. 

If the engine speed is below the predetermined level, the engine management unit will not allow the 

feed rollers to work in the forward “infeed” direction, until the rotor speed rises above the 

predetermined level. At this point, the feed rollers will start turning without warning. The reverse 

function will work at any engine speed. 

EMERGENCY STOPPING 

There are two ways of stopping the TW 190TDHB (Turbo) chipper in the event of an emergency. 

STOPPING THE ROLLERS 

-Activating the red safety bar will stop the rollers immediately. To restart the rollers, just push the 

green forward button or blue reverse button. 

-Pushing the red Emergency button on the roller control box will also stop the rollers immediately. The 

button will stay in the “pushed in” position, and will require resetting (pulling out) before being able to 

restart the roller functions. 

DAILY CHECKS BEFORE STARTING 

LOCATE the machine on firm level ground. 

CHECK machine is well supported and 

cannot move. 

CHECK jack stand is lowered and secure. 

CHECK all guards are fitted and secure. 

CHECK the discharge unit is in place and 

fastened securely.

Controlling the discharge is an essential part of safe working. 

BUCKET ANGLE 

1. Slacken nut using 

integral handle.

4. Adjust the bucket to the desired 

angle using the handle provided. 

2. Rotate tube. 

3. Retighten nut.


CHIPPING 

Wood up to 190 mm diameter can be fed into the feed funnel. Put the butt end in first and engage it 

with the feed roller. The hydraulic feed rollers will pull the branch into the machine quite quickly. Large 

diameter material will have its feed rate automatically controlled by the engine management unit. 

Sometimes a piece of wood that is a particularly awkward shape is too strong for the feed rollers to 

break. This will cause the top roller to either bounce up and down on the wood or both rollers to stall. 

If this occurs press the BLUE REVERSE button until the material has been released. Pull the material 

out of the feed funnel and trim it so the chipper can handle it. 

Both feed rollers should always turn at the same speed. If one or both rollers stop or suddenly slow 

down it may be that a piece of wood has become stuck behind one of the rollers. If this occurs press 

the BLUE REVERSE button and hold for 2 seconds - then repress GREEN FEED button. This should 

enable the rollers to free the offending piece of material and continue rotation at the correct speed. If 

the rollers continue to stall in the 'forward feed' or 'reverse feed' position push the RED STOP 

BUTTON, turn engine off, remove ignition key and investigate. 

BLOCKAGES 

Always be aware that what you are putting into the chipper must come out. If the chips stop coming 

out of the discharge tube but the chipper is taking material in - STOP IMMEDIATELY. Continuing to 

feed material into a blocked machine may cause damage and will make it difficult to clear. 

If the chipper becomes blocked proceed as follows: 

STOP the engine and remove the keys. 

REMOVE the two rotor housing bolts. 

OPEN the rotor housing fully. 

THE material causing the blockage should fall clear. 

WARNING 

Do not reach into the rotor housing with unprotected hands. There are 

sharp blades and any small movement of the rotor may cause serious injury. 

! ! 

EMPTY loose debris from inside the rotor housing. 

CHECK that the discharge tube is clear before continuing. 

THE rotor housing does not have to be completely clear to continue. 

SHUT the rotor housing and replace both bolts securely. 

RESTART the engine. 

ALLOW machine time to clear excess chips still remaining in rotor housing before you continue 

feeding brushwood. Feed in a small piece of wood while watching to make sure that it comes out of 

the discharge. If this does not clear it, repeat the process and carefully inspect the discharge tube to 

find any obstruction. 

NOTE 

Continuing to feed the chipper with brushwood once it has become blocked will cause the chipper to 

compact the chips in the rotor housing and it will be difficult and time consuming to clear. 

AVOID THIS SITUATION - WATCH THE DISCHARGE TUBE AT ALL TIMES.

CHANGING BLADES 

WARNING 

Wear heavy duty gloves for the blade changing operation. 

1. Turn off the chipper and remove the key. 

2. Remove the negative battery lead. 

3. Turn the discharge tube to point across the 

machine. 

4. Use a 24mm socket with extension bar to 

remove the two M16 nuts clamping the rotor 

housing shut. 

5. Carefully lift the rotor housing until its rests on 

its stop. 

6. Using the fan blades turn the rotor so the first 

blade to be changed is in a convenient 

position. Wedge rotor against the housing 

with a wooden block to prevent turning. 

7. Brush away all dirt and debris from the rotor 

and blades. 

8. With a 24mm spanner/socket undo the two 

nyloc nuts that are holding the blade in place. 

9. Grasp the blade by the flat edges while 

wearing heavy duty gloves. 

10. Withdraw the blade from the rotor. 

11. If the blades are being rotated and not 

replaced, do not remove the blade bolts. 

12. If the blades are to be renewed, place the 

blade on a flat surface and tap the top of 

the blade bolts with a hammer. The bolts 

are designed for this. They should loosen 

from the blade. Withdraw them completely. 

13. Clean the back surface of the blade, blade 

bolts and blade area of the rotor before 

WARNING 

Always sharpen blades on a regular basis. Failure to do so will cause the machine 

to under perform and will overload engine and bearings causing machine 

breakdown. Blades must not be sharpened beyond the wear mark (see diagram). 

! Failure to comply with this could result in machine damage, injury or loss of life.

reseating blades. The blades must not 

have any material underneath them 

when tightened. If they are not flat and 

tight they will become loose quickly. 

14. Reassemble the blades, bolts, washers and 

nuts in the order shown in the diagram 

above. Use only genuine Timberwolf nuts 

and washers, as they are of a higher grade 

than normally stocked at fastener factories. 

Failure to use the appropriate grade nuts or 

washers may result in damage, injury or 

death. The use of genuine Timberwolf 

blades and bolts is recommended. 

15. Apply a smear of anti seize compound 

(copper ease) to the bolt threads and back 

face of the nuts. Do not apply copper grease 

onto the counter bore faces of the blades or 

bolts. 

16. Wedge rotor against housing with a wooden 

block to tension nuts. 

17. A calibrated torque wrench must be used 

to tighten the bolts to a torque setting of 

125 lbs ft (170 Nm). 

18. Repeat this procedure for the other blade. 

19. Slowly lower the rotor housing to its original 

position. 

20. Refit the two M16 nuts and tighten to 

60 lbs ft (80Nm). 

21. Re-attach battery lead.

CHECK FITTINGS 

The TW 190TDHB (Turbo) is subject to large vibrations during the normal course of operation. 

Consequently there is always a possibility that nuts and bolts will work themselves loose. It is 

important that periodic checks are made to ensure the security of all fasteners. Uncalibrated torque 

wrenches can be inaccurate by as much as 25%. It is therefore essential that a calibrated 

torque wrench is used to achieve the tightening torques listed below.

CHECK HOSES 

All the hydraulic hoses should be regularly inspected for chafing and leaks. The hydraulic system is 

pressurized to 150 Bar (2175 PSI) and thus the equipment containing it must be kept in good condition. 

Identify the hoses that run to the top motor. These have the highest chance of damage as they are 

constantly moving. If any hydraulic components are changed new seals should be installed during 

reassembly. Fittings should then be retightened. 

TENSION DRIVE BELTS 

NOTE: There will normally be a rapid drop in tension during run-in period for new belts. When new 

belts are fitted, check the tension every 2 - 3 hours and adjust until the tension remains constant. 

Belt failures due to lack of correct tensioning will not be covered under your Timberwolf warranty. 

1. Remove the near side roller box guard. 

2. Open the rotor housing. 

3. Slacken the four 24 mm nuts that retain the 

roller box (bolt is retained underneath). 

4. Slacken the lock nuts on the belt tension bracket. 

5. Turn appropriate lock nut to move roller box in 

desired direction. Take care to keep roller box 

square. Slightly tighten nut A (see diagram) 

when tension is near desired amount. Continue 

to tension belts until correct tension is achieved. 

3 

A 

For instructions on checking belt tension & 

correct belt tension values, please refer to 

the Timberwolf V-Belt Tensioning Data Table 

(pg. 45). 

6. When the belt tension is correct tighten 

the four 24 mm roller box retaining nuts. 

7. Tighten the lock nuts. 

8. Grease the roller box slides and rollers. 

9. Close the rotor housing and fasten securely. 

10. Refit the near side roller box guard. 

4


GREASE THE ROLLER BOX SLIDES 

NOTE: This should be done every 50 hours. In dirty or dusty conditions or during periods of 

hard work it should be done more frequently. If the slides become dry the top roller will tend 

to hang up and the pulling-in power of the rollers will 

be much reduced. Excessive wear will ensue. 

1 

1. Remove the near side roller box guard. 


3. Apply multipurpose grease directly to the slide surfaces 

indicated. DO NOT USE GRAPHITE BASED GREASE. 

4. Close the rotor housing. 

5. Refit the near side roller box guard. 

GREASE THE ROLLER SPLINE AND BEARING 

NOTE: This should be done regularly. In dirty and dusty conditions or during periods of hard 

work it should be weekly. If the bearings and splines are allowed to run dry premature wear 

will occur resulting in a breakdown and the need for replacement parts. This failure is not 

warranty. Early signs of insufficient grease includes squeaking or knocking rollers. 


2. Locate two grease nipples; one in the centre of each roller shaft. 

3. Use a pump action grease gun to apply a generous amount of grease to 

each roller drive. DO NOT USE GRAPHITE BASED GREASE. 

4. Close the rotor housing. 

5. To penetrate all the bearing surfaces thoroughly, start the machine and 

operate the rollers for 20 seconds. Switch off the machine. Repeat this 

greasing/running procedure a further 3 times. 

GREASE THE JACK STAND 

The jack stand requires intermittent greasing to maintain a smooth operation. 

1. Brush off dirt with a stiff brush. 

2. Apply grease liberally to screw thread using a brush. 

3. Wind mechanism up and down a couple of times to ensure grease has covered all surfaces. 

2 

GREASE THE DISCHARGE FLANGE 

1. Remove the discharge tube. 

2. Apply multipurpose grease to surface shown. 

3. Refit discharge tube. 

GREASING ROTOR BEARINGS 

Both front and rear bearings are sealed and do not need greasing.

TIMBERWOLF V-BELT TENSIONING DATA TABLE 

METHOD: 

1. SET THE DEFLECTION DISTANCE ON THE LOWER SCALE OF THE TENSION GUAGE 

SO THAT THE UNDERSIDE OF THE 'O'-RING EQUALS THE 'h' VALUE GIVEN IN THE 

TABLE BELOW 

V-BELT TENSIONING TABLE 46 

TIPS ON BELT TIGHTENING: 

A) THERE WILL NORMALLY BE A RAPID DROP IN TENSION DURING THE 

RUN-IN PERIOD FOR NEW BELTS. WHEN NEW BELTS ARE FITTED, CHECK THE 

TENSION EVERY 2-3 HOURS & ADJUST UNTIL THE TENSION REMAINS 

CONSTANT 

2. ENSURE THAT THE DEFLECTION FORCE SCALE IS ZERO'D BY PUSHING THE UPPER 

'O'-RING ALL THE WAY DOWN 

= 

= 

3. PLACE THE TENSION GUAGE IN THE CENTRE OF THE BELT SPAN AS SHOWN IN 

THE DIAGRAM LEFT 

B) THE BEST TENSION FOR V-BELT DRIVES IS THE LOWEST TENSION AT 

WHICH THE BELTS DO NOT SLIP OR RATCHET UNDER THE HIGHEST LOAD 

CONDITION 

4. PRESS DOWNWARDS ON THE RUBBER BUFFER, DEFLECTING THE BELT UNTIL THE 

UNDERSIDE OF THE LOWER O'-RING IS LEVEL WITH THE BELT BEHIND (USE A 

STRAIGHT EDGE IF THERE IS ONLY 1 BELT) 

h 

C) TOO MUCH TENSION SHORTENS BELT & BEARING LIFE 

D) TOO LITTLE TENSION WILL AFFECT THE PERFORMANCE OF YOUR MACHINE 

ESPECIALLY IN RESPECT OF NO-STRESS DEVICES 

5. TAKE THE READING FROM THE DEFLECTION SCALE OF THE TENSION METER 

(READ AT THE LOWER EDGE OF THE 'O'-RING) & COMPARE THIS VALUE WITH 

THAT GIVEN IN THE TABLE BELOW 

E) ENSURE THAT BELT DRIVES ARE KEPT FREE OF ANY FOREIGN MATERIALS 

6. TIGHTEN OR LOOSEN BELTS AS REQUIRED FOLLOWING PROCEDURE GIVEN IN THE 

OPERATOR'S MANUAL 

F) IF A BELT SLIPS - TIGHTEN IT! 

TENSION GUAGES ARE AVAILABLE FROM TIMBERWOLF SPARES, QUOTING PART No. 18091
